Table 5–77. Maximum Input Toggle Rate on Stratix II Devices (Part 1 of 2)
Input I/O Standard
The maximum clock toggle rate is different from the maximum data bit
rate. If the maximum clock toggle rate on a regular I/O pin is 300 MHz,
the maximum data bit rate for dual data rate (DDR) could be potentially
as high as 600 Mbps on the same I/O pin.
Table 5–77
specifies the maximum output clock toggle rates at 0pF load.
specifies the derating factors for the output clock toggle rate for a non 0pF
load.
To calculate the output toggle rate for a non 0pF load, use this formula:
The toggle rate for a non 0pF load
For example, the output toggle rate at 0pF load for SSTL-18 Class II 20mA
I/O standard is 550 MHz on a -3 device clock output pin. The derating
factor is 94ps/pF. For a 10pF load the toggle rate is calculated as:
